BACKGROUND OF THE INVENTION 1. Technical Field

The invention relates generally to eyewear devices, and more particularly to apparatuses, methods, and systems for providing information to a user through a modularized eyewear device.

2. Background

The pace of modern life moves at a fast past. A person is often placed under the constraint of time and is placed in situations where his or her hands are occupied and information is not accessible to the person. This can present a problem. Currently available eyewear such as prescription glasses, e.g., prescription reading glasses or prescription sunglasses are expensive and are not readily reconfigured to different user's needs. This can present a problem. Personalized sound transmission is often done with an occlusive in ear device known as an earphone or earbud. Such a device obstructs the ear canal and can interfere with a user's hearing of far field sounds. This can present a problem. Thus, problems exist that requires technical solutions that uses technical means to produce technical effects.

DETAILED DESCRIPTION

In the following detailed description of embodiments of the invention, reference is made to the accompanying drawings, in which like references indicate similar elements, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those of skill in the art to practice the invention. In other instances, well-known circuits, structures, and techniques have not been shown in detail in order not to obscure the understanding of this description. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims.

In one or more embodiments, methods, apparatuses, and systems are described, that provide modularization of an eyewear system for a user. As described in the description of embodiments below, various combinations and configurations of electronics are taught for incorporation into eyewear devices. Some electronics configurations are removably couplable to an eyewear device. In some embodiments, an electronics configuration is built-into an eyewear device. In yet other embodiments, a behind the neck module assembly is releasably couplable with an eyewear device. In various embodiments, the modularized reconfigurable eyewear devices provide information to a user through the eyewear device. As used in this description of embodiments, information includes streaming audio in the form of music, information also includes parameters of a user's biology (e.g., biometrics of physiology, biomechanics, etc.) such as, but not limited to; heart rate, breathing rate, posture, steps, cadence, etc. Information also includes information of interest to a user such as, but not limited to; information on a vehicle that a user is using such as; revolutions per minute (RPM) of a bicycle, engine parameters such as RPM, oil pressure, cooling water temperature, wind speed, depth of water, air speed, etc. In various embodiments, information is presented to a user through an eyewear device by, for example, an audio broadcast that a user hears and a video broadcast to a display that the user sees in the eyewear device, or sees as an image as projected onto a pupil of the user's eye. Thus, information is to be given an expansive meaning within the scope of embodiments taught herein.

FIG. 1 illustrates a modular reconfigurable eyewear system, according to embodiments of the invention. With reference to FIG. 1, a modularized eyewear device is shown in perspective view at 100. The modularized eyewear device 100 has a frame chassis 102. In various embodiments, the frame chassis 102 is ophthalmically constructed to provide frame rim portions that hold lens 120 and lens 122. The lens 120 and 122 can provide any of the functions that eyewear devices provide, such as but not limited to, a safety glass lens, a prescriptive lens, a sunglass lens, a welding glass lens, etc. An eyewear device can also contain a single lens instead of the dual lens illustrated. In some embodiments, a nose pad is provided, thereby providing a cushion for the contact zone with a user's nose. In some embodiments, the nose pad is made from a compliant material such as silicon rubber.

A temple 104 (left temple) and a temple 114 (right temple) are coupled to the frame chassis 102. The temples 104 and 114 can be flexibly coupled to the frame chassis 102, with hinges as shown in the figure or the temples 104 and 114 can be provided with a fixed orientation relative to the frame chassis 102.

In various embodiments, one or more temples (104 and 114) and the chassis frame 102 can be fitted with electronics as described below. Within the view of 100, a left temple insert module (TIM) 106 is configured with the left temple 104 and a right temple insert module (TIM) 116 is configured with the right temple 114. Temple insert modules (TIMs) are described more fully in conjunction with the figures below.

With continued reference to FIG. 1, a modularized eyewear device is shown in exploded view at 130. A frame chassis 132 is ophthalmically constructed to encircle a lens 140 and a lens 142 with a frame rim thereby securing the lens 140 and the lens 142 thereto. A brow bar 146 is fastened to the frame chassis 132 in various ways, via assembly fasteners, adhesive, etc. A left temple 144 includes a left temple connector 152 which is rotatably coupleable with a left chassis connector 150. Together, the left chassis connector 150 and the left temple connector 152 form a rotatable mechanical and electrical connection between the chassis 132 and the left temple 144, thereby providing one or more electrical pathways to connect the frame chassis 132 to the left temple 144. Similarly, a right temple 134 is rotatably coupleable to the frame chassis 132 through a right hinge assembly 148.

Note that in some embodiments, a modularized eyewear device is configured such that each temple can be removed from its hinge via an electrical/mechanical connector having one or more electrical contacts, not shown for clarity in the illustration. These electrical contact points can be made using, for example, pins, points, pads, slots, contact devices, etc. For example, the line indicated at 154 demarcates the mating of the right temple connector with the right temple 134. Similarly, the line indicated at 156 demarcates the mating of the left temple connector 152 with the left temple 144.

Through the provision of electrical/mechanical connectors between each temple, e.g., 134, 144 and the frame chassis 132 the temples are interchangeable with the eyewear device. This functionality permits a user to interchange one temple with another. Different temples can be configured with different electronics to provide different functionality as described herein. Either temple can be configured to accommodate various electronics configurations. For example, in one or more embodiments, the right interchangeable temple accommodates an electronics package that can include one or more of; a biometric sensor, a biomechanical sensor, a vehicle sensor, an environmental sensor, a temperature sensor, an acoustic sensor, a motion sensor, a light sensor, a touch sensor, a proximity sensor, a velocity sensor, an acceleration sensor, a rotation sensor, a magnetic field sensor, a global position system (GPS) receiver, cables, microphones, a micro speaker, a source of electrical power (battery), a camera, a micro display, a heads-up display (HUD) module, a multiaxis inertial measurement unit, a wireless communications system. Note that a TIM can also contain the electronics package and sensor(s) described above. In various embodiments, one or more wireless communication system are provided that utilize for example; near-field communications (NFC) using the industrial-scientific-medical (ISM) frequency of 13.56 MHz, the Adaptive Network Topology (ANT) ANT+ wireless standard, wireless communications using a Bluetooth standard, a Bluetooth low energy standard (BLE), wireless communication using a Wi-Fi standard, and wireless communication using mobile telephone standards such as for example the 3G, 4G, Long Term Evolution (LIE), 5G, etc. standard or other wireless standards. In some embodiments, electrical pathways from the electronics exit a temple via a sheath cavity and travel into a temple sheath and continue into a brow bar sheath cavity. The right interchangeable temple contains a hinge-connector 148 that fastens to the brow bar 146 and chassis frame 132.

In one or more embodiments, the right interchangeable temple attaches to the front of the frame chassis via a hinge-connector that allows for power and data transferred to the left interchangeable temple through the modular brow bar. The hinge-connector mechanically interlocks with the frame chassis and allows for power/data connectivity with electrical pin conductors. In one or more embodiments, when positioned in the open direction of wearing, the hinge-connectors sense the open state of the device allowing for power or data transfer. When in the closed position (temples folded inward), the hinge-connector in conjunction with signals received from one or more of proximity sensors and motion sensors will allow the system to sense the user-device interaction state and will deactivate the power or data transfer. This function leads to reduced power consumption when folded and stowed and can lead to automatic power up while a user wears the device on his or her head. In addition to switchable data or power transfer from the hinge-connector, the hinge-connector can provide flexible circuits and wired micro-connectors that provide steady uninterrupted power and or data transfer.

In some embodiments, it is convenient to route electrical pathways within a volume of the brow bar 146. In some embodiments, the brow bar 146 is constructed to provide a channel along its length, within which the electrical pathways are routed. Thus, the brow bar 146 provides one or more sheaths, channels, etc. along its length within which electrical pathways and sensors can be contained. Examples of electrical pathways are, but are not limited to; wires, printed circuit board, flexible printed circuit board, etc. In various embodiments, it is advantageous to mount one or more sensors to the brow bar 146, thereby making an electrical sub-assembly for the frame chassis 132. In some embodiments, additional electrical pathways from the frame chassis 132 are joined with the electrical pathway contained in the brow bar 146. In some embodiments, a flexible electronic circuit is adhered to the underside top face of the brow bar and exits the brow bar via the left and right sheath cavities. Alternatively, or in combination, fully embedded flexible electronics may be cast into the brow bar with integrated contact points exiting the brow bar near each hinge. These integrated contact points on both sides of the brow bar allow transmission of data or power when in contact with the integrated contact points of the right and left temple. In addition to facilitating connection to electronics, the brow bar can conceal an optional pupil module by a securing flange and allows the user to view a microdisplay via the brow bar pupil aperture.

In similar fashion the left temple is configured as a left interchangeable temple connected to the front frame of the eyewear with a left hinge-connector. In various embodiments, the left interchangeable temple can contain the same electronics configuration/functionality as the right interchangeable temple or interchangeable temples can contain different electronics configurations and different functionality.

With continued reference to FIG. 1, a left temple 164 and right temple 174 are configured as shown at 160. Each of the temples 164 and 174 contain electronics which are configured to provide information and functionality to a user of the eyewear system. As shown at 160, the left temple 164 has a temple door (not shown) removed thereby exposing an electronics package indicated at 186. The temple door secures and protects electronics from environmental exposure and hazard. The temple door is secured to the temple assembly with suitable mechanical fasteners for a given application. In some embodiments, the temple door provides a rating with respect to water intrusion via an IP Code from International Protection Marking IEC standard 60529. A source of electrical power (battery) is illustrated at 184 and an audio speaker and port is illustrated at 182. The audio speaker and port 182 is generally located on a posterior end of a temple and in some embodiments is an integrated directional projection speaker that privately directs sound to a user's ear. Projection stereo speakers can communicate various audio signals to the user, such as but not limited to, voice prompts, streaming music, smart audio assistance, data, etc. Notably, the projection speaker design does not occlude the user's ear. Thus, the user can hear far field sounds and the far field sounds are not degraded as they are with currently available earbud style headphones that occlude a user's ear.

The right temple 174 is also provided with an electronics package (not shown in the view) contained within the right temple 174. The right temple is provided with an audio speaker with audio speaker port 184, which can be an integrated directional projection speaker. In one or more embodiments, the right temple 174 is configured to accommodate an external assembly 190 that contains a micro display assembly 192. Similarly, the left temple could be configured for the external assembly 190 and the micro display assembly 192.

In various embodiments, a micro display assembly, such as 192, is a head up display (HUD) Pupil™ Optics Module that houses the optics, electronics, and micro display that form the optical system. The pupil mechanism also may house cables, flexible circuit boards, or wires which exit from a housing into an electronics contact pathway. In one or more embodiments, these electrical pathways are connected to a side of the left temple 174 to enable the user with a see-through head up display external accessory to enhance a visual component of a mobile reality experience.

In one or more embodiments, wiring which exits the brow bar is concealed in the right and left sheaths of the temples and enters into the right and left temples via the sheath cavities, thereby protecting the wiring from environmental hazards. The area near the contact pathway may also accommodate motion mechanisms for customizing the interpupillary distance of the head-up micro display module.

In different embodiments, the front frame portion, such as 102 or 132 (FIG. 1) or any similar structure in the figures below, and the right and left temple portions, such as 104, 114, 134, 144, 164, 174 (FIG. 1) or any similar structures in the figures below, can be part of a set of interchangeable front frame portions and temple portions each having the same or different combinations of devices, accessories, capabilities and/or functions. At least one of an electronics board, microphones, speakers, battery, camera, heads-up display module, wireless Wi-Fi radio, GPS chipset, LTE cellular radio, multiaxis inertial measurement unit, motion sensor, touch sensor, light and proximity sensors, etc. can be included in desired combinations. Electronics can be further included that permit a user to perform at least one of; wirelessly connecting to a cellular service, a smart phone, a smart watch, a smart bracelet, a mobile computer, and a sensor peripheral. The electronics can further include the ability to; view see-through augmented reality images via a modular head up display (HUD), provide stereo audio content, provide voice and audio notification including music through one or more integrated projection micro-speakers. The front frame electrical contact devices and the temple electrical contact devices can include electrical contact points in or near respective hinge connectors for removable electrical contact with each other for electrically transmitting at least one of; power, electrical signals and data between the temple portions and the front frame portion when the contact points are in an electrically closed position. In some embodiments when assembled together, the front frame hinge connectors, the front frame electrical contact devices, the temple hinge connectors and the temple electrical contact devices can form electromechanical hinges, hinge connectors, assemblies or devices. In some embodiments, system electrical power can be turned off by folding the temple portions into a storage position thereby disconnecting the contact points.

In some embodiments, at least one of the front frame electronics and the temple electronics can include at least one of a battery, camera, heads-up display module, controller, digital storage electronics, CPU, projection micro-speaker, microphone, wireless Wi-Fi radio, GPS chipset, LTE cellular radio, multiaxis inertial measurement system or unit, and sensory, motion, touch, light, proximity, temperature and pressure sensors, etc.

In some embodiments, at least one temple can include a temple module insert (TIM) containing selected temple electronics, mounted thereto. In other embodiments, a neck smart cord is electrically connected to a behind the neck electronics module. The neck smart cord has right and left connectors or connector ends for mechanically and or electrically interconnecting the behind the neck electronics module with the right and left temples of an eyewear device.

FIG. 2 illustrates a reconfigurable component for an eyewear device, according to embodiments of the invention. With reference to FIG. 2 at 200, a temple 202 is provided with an engagement portion 204. A temple insert module, referred to in this description of embodiments as a “TIM” at 210 is configured to be releasably coupleable with the engagement portion 204 of the temple 202. The TIM 210 is installed into the temple 202 as indicated by arrows 212 a and 212 b. In various embodiments, the engagement portion 204 is accomplished by a mechanical connection, such as but not limited to; press fit, clip, mechanical interlock, hook and loop, magnetic surface, external clamp to temple, flange and mechanical coupling to temple, etc. In yet other embodiments the engagement portion 204 and the TIM 210 utilize magnetic surfaces, thereby holding the TIM 210 secure by magnetic attraction. The form of the engagement portion shown at 204, as well as the form of any engagement portion illustrated elsewhere in the figures presented herein, is given merely for illustration and does not limit embodiments of the invention. In the view illustrated at 200, the TIM 210 only makes a mechanical connection with the temple 202 no electrical connection is provided between the TIM 210 and the temple 202.

In some embodiments, the TIM 210 is provided with a speaker and speaker port 214, which can be a micro projection speaker. The speaker provides information to a user through an audio broadcast. Note that the speakers provided herein are speakers that are located externally from a user's ear and are therefore not inserted into the user's ear like an earbud is inserted. The TIM 210 is configured with an electronics package that contains a processor, memory, electrical power, and one or more wireless communication protocols that enable the TIM 210 to communicate wirelessly 222 with one or more devices 220. The device 220 can be an external sensor such as, but not limited to; a biometric sensor or a vehicle sensor, a local user device, a network node, such as a wireless router, a remote network, or a remote user device such as a mobile phone accessed through a network. Different sensors, networks, and remote devices are described more fully in conjunction with the figures below.

Following the architecture of FIG. 2 at 200, in some embodiments, a second temple and a second TIM are provided. The two TIMs in such a system can engage in wireless communication between the device 220 and between themselves as needed to provide a level of design functionality to a user. For example, in one embodiment, a left TIM includes wireless network capability sufficient to communicate with the remote device 220, utilizing a first network protocol. In addition, the left TIM and the right TIM are provided with wireless network capability that supports communication utilizing a second network protocol. In order to conserve electrical power, the first network protocol has a greater range than the second network protocol because a distance between the left TIM and the remote device is greater than a separation distance between the left TIM and the right TIM (nominally a width of user's head). The architecture illustrated at 200 is referred to as true wireless because there is no wired connection between the left TIM and the right TIM. In one or more embodiments, an audio stream is provided from a user device to a first TIM utilizing a first wireless network. Then a second wireless audio stream is provided from one TIM to the other TIM utilizing a second wireless network in order to provide the audio stream to each of a left and a right projection speakers of the eyewear device.

The temples and TIMs described at 200 provide reconfigurable components for eyewear devices as described in conjunction with the figures herein. A forward end 206 of the temple 202 is engageable with a frame chassis of an eyewear device as described above with or without a connector between a temple and a frame. Thus, the temple 202 can attain a fixed position relative to a frame chassis or the temple can be rotatably coupled to the frame chassis depending on a give design of the eyewear.

With reference to FIG. 2 at 250, a temple 252 is provided with an engagement portion 254. A temple insert module, TIM at 260, is configured to be releasably coupleable with the engagement portion 254 of the temple 252. The TIM 260 is installed into the temple 252 as indicated by arrows 262 a and 262 b. In various embodiments, the engagement portion 204 is accomplished by a combined electrical and mechanical connection. The mechanical connection can be as described in conjunction with 210/204 such as, but not limited to; press fit, clip, mechanical interlock, hook and loop, etc. In yet other embodiments the engagement portion 254 and the TIM 260 utilize magnetic surfaces, thereby holding the TIM 260 secure by magnetic attraction. A number of electrical contacts 280 are provided for illustration with no limitation implied thereby. The electrical contacts 280 mate with corresponding electrical contacts in the temple 252 thereby providing electrical connection to one or more electrical pathways (not shown) in the temple 252. The electrical pathways within the temple 252 facilitate electrical connection between the TIM 260 and one or more sensors 272 and 274, which can also represent a source of signals provided to a display(s). The sensors 272 and 274 can be acoustic sensors such as microphones or any of the sensors described herein for use in conjunction with electronics packages configured with eyewear devices. In one or more embodiments, one or more of 272 and 274 provide signals to a display such as a HUD.

In some embodiments, the TIM 260 is provided with a speaker and speaker port 264, which can be a micro projection speaker. The speaker provides information to a user through an open-ear audio broadcast.

Following the architecture of FIG. 2 at 250, in some embodiments, a second temple and a second TIM are provided, as shown below in FIG. 3. The two TIMs in such a system engage in wireless communication between the device 220 and between themselves as needed to provide a level of design functionality to a user. The temples and TIMs described at 250 provide reconfigurable components for eyewear devices as described in conjunction with the figures herein. For example, a forward end 256 of the temple 252 is engageable with a frame chassis of an eyewear device as described above with or without a connector between a temple and a frame. Thus, the temple 252 can attain a fixed position relative to a frame chassis or the temple can be rotatably coupled to the frame chassis depending on a given design of the eyewear.

FIG. 3 illustrates, at 300, multiple reconfigurable components for an eyewear device, according to embodiments of the invention. With reference to FIG. 3 at 300, the left reconfigurable component 250 from FIG. 2 is illustrated with a companion right reconfigurable component for an eyewear device. A right temple 352 has an engagement portion that is not shown in FIG. 3 but is similar to the engagement portion 254 of the left temple 252. A temple insert module, TIM at 360 is configured to be releasably coupleable with the engagement portion of the temple 352. The TIM 360 is couple with the temple 352 as indicated by arrows 362 a and 362 b. In various embodiments, the engagement portion of the temple 352 is accomplished by a combined electrical and mechanical connection. The mechanical connection can be provided as described above in conjunction with 210/204 such as, but not limited to; press fit, clip, mechanical interlock, hook and loop, etc. In yet other embodiments the engagement portion of the temple 352 and the TIM 360 utilize magnetic surfaces, thereby holding the TIM 360 secure by magnetic attraction. Several electrical contacts 380 are provided for illustration with no limitation implied thereby. The electrical contacts 380 mate with corresponding electrical contacts in the temple 352 thereby providing electrical connection to one or more electrical pathways (not shown) in the temple 352. The electrical pathways within the temple 352 facilitate electrical connection between the TIM 360 and one or more sensors 372 and 374. The sensors 372 and 374 can be acoustic sensors such as microphones or any of the sensors or displays described herein for use in conjunction with electronics packages configured with eyewear devices. In various embodiments, the TIM 360 is configured with an electronics package that contains a processor, memory, electrical power, and one or more wireless communication systems using protocols that enable the TIM 360 to communicate wirelessly as indicated by a wireless transmission at 222 with one or more devices 220. In addition, the TIM 360 and the TIM 260 can be configured with wireless communication capability that permits wireless communication between the TIMs as indicated by a wireless transmission at 382. In some embodiments, the TIM 360 is provided with a speaker and a speaker port indicated at 364, which can be a micro projection speaker. The speaker provides information to a user through an audio broadcast.

With reference to view 390 of FIG. 3, electrical connectivity schematics are illustrated for each of TIM 260 and TIM 360. The TIM 260 is electrically coupled to the sensor 272 with an electrical pathway 394. Similarly, the TIM 260 is electrically coupled to the sensor 274 by an electrical pathway 392. The connectivity illustrated between the TIM 260 and the respective sensors constitutes a left temple electrical schematic 384. Note that the left temple electrical schematic 384 can be more complex or less complex that the illustration. Thus, the left temple electrical schematic is provided merely for illustration with no limitation implied thereby.

Similarly, the TIM 360 is electrically coupled to the sensor 372 with an electrical pathway 398. The TIM 260 is electrically coupled to the sensor 374 by an electrical pathway 396. The connectivity illustrated between the TIM 360 and the respective sensors constitutes a right temple electrical schematic 386. Note that the right temple electrical schematic 386 can be more complex or less complex that the illustration. Thus, the right electrical schematic is provided merely for illustration with no limitation implied thereby.

The two TIMs in such a system engage in wireless communication between the device 220 and between themselves as needed to provide a level of design functionality to a user. For example, in one embodiment, a left TIM includes wireless network capability sufficient to communicate with the remote device 220, utilizing a first network protocol. In addition, the left TIM and the right TIM are provided with wireless network capability that supports wireless communication as indicated at 382. The wireless communication 382 can be performed with a second network protocol, which is different from that used at 222. In order to conserve electrical power, the first network protocol (222) has a greater range than the second network protocol (382) because a separation distance between the left TIM 260 and the remote device 220 is greater than a separation distance between the left TIM 260 and the right TIM 360, the latter is nominally a width of user's head and the former can be as much as a distance to a mobile telephone cellular tower.

FIG. 4 illustrates another reconfigurable modularized eyewear system, according to embodiments of the invention. With reference to FIG. 4, one or more of sensors, power components, and computational units are distributed throughout an eyewear device, including distributed throughout a frame chassis such as 402. A frame chassis 402 is ophthalmically constructed to encircle lens 440 with frame rims thereby securing the lens 440 thereto. A left temple 404 are a right temple 414 are coupled to the frame chassis 402, thereby forming an eyewear device. The left temple 404 is configured with an engagement portion indicated at 408. A left temple insert module (TIM) 406 is configured as described above to engage with the engagement portion 408, thereby providing both mechanical and electrical connection between the TIM 406 and the temple 404. Similarly, a right temple 426 is illustrated as engaged with the engagement portion of the right temple 414. The TIM 406 contains an audio speaker and audio port indicated at 410 and the TIM 426 contains an audio speaker and audio port indicated at 430. In various embodiments, the audio speakers of 410 and 430 are projection speakers. The eyewear device includes several sensors or display(s), 462, 464, 466, 468, and 470 that are integrated into an electrical pathway that extends from the left temple 404 through the frame chassis 402 to the right temple 414. In various embodiments there can be more sensors or less sensors that those shown in FIG. 4. The sensors and the locations of the sensors shown in FIG. 4 are provided merely as an illustration and do not limit embodiments of the invention.

-   -   LED 1620—via GPIO output pin.     -   Button 1614—via GPIO input pin.     -   Touch sensor 166—via GPIOs input and output pins.     -   Voice wake-up chip 1608—via GPIO and UART.     -   Proximity sensor 1618—via I2C bus.     -   Microphone 1604/1606 & speaker 1628—via analog-digital-converter         (ADC) 1640 and digital-to-analog-converter (DAC) 1636.     -   6+3 axis sensors—via I2C bus.

FIG. 17 illustrates a schematic block diagram for wakeup control, according to embodiments of the invention. Referring to FIG. 17, the system 1702 will enter sleep mode 1704 in order to save battery power. A voice wake-up chip, such as for example 1608, is used to detect a wake-up word 1710 (for example “SOLOS” spoken by a user and received on a microphone such as 1604). If the wake-up word 1710 is detected at 1608, the CPU/System is powered up and moves to a “RUN” state as indicated at 1706.

The systems 1700, 1702 or 1600 illustrated in conjunction with FIG. 16 and FIG. 17, utilize an embedded speech recognition system 1608. Examples, of embedded speech recognition systems for use in embodiments of the invention are, but are not limited to, the embedded speech recognition systems from NUANCE such as the VoCon Hybrid, etc. or embedded speech recognition systems from other manufacturers. The data sheet for the NUANCE VoCon Hybrid is included herein as APPENDIX 1.

Referring to FIG. 16 and FIG. 17, in operation, when idle, the System 1702 is in “SLEEP” mode whereas the DSP VoCon 1608 is always “ON” so that it can detect the wake-up word 1710 via an input from the connected microphone 1604. When the DSP VoCon system 1608 detects the wake-up word 1710, a wakeup control signal 1714 is sent to move the System 1702 from “SLEEP” mode 1704 to “RUN” mode 1706.

The embedded speech recognition system 1608 is used to process wake-up word(s) 1710 and it is also used for command and control of the head wearable device from commands extracted from a user's speech.

In various embodiments, the components of system shown in FIG. 16 and/or FIG. 17 are implemented in an integrated circuit device, which may include an integrated circuit package containing the integrated circuit. In some embodiments, the components of the system(s) are implemented in a single integrated circuit die. In other embodiments, the components of the system(s) are implemented in more than one integrated circuit die of an integrated circuit device which may include a multi-chip package containing the integrated circuit.

In various embodiments, six (6) axis sensors, illustrated at 1624, and three (3) axis sensors, illustrated at 1622, are used to perform heading, tracking, and e-compass functions. In one embodiment, provided merely for illustration and with no limitation implied thereby, the sensors capture the following nine (9) axis data (at rate of 10 samples/second) which can be used by a mobile communications unit (MCU) 1602 to calculate movement of a user's head. The nine (9) axes of data are, but are not limited to: acceleration data measured from accelerometers along X, Y, and Z axes; gyroscope data from X, Y, and Z axes; and magnetometer data from X, Y, and Z axes. It is understood by those of ordinary skill in the art that X, Y, and Z axes imply an orthogonal coordinate system. In some embodiments, these sensor data are used to track the trajectory of user's movement while wearing a head wearable device.

FIG. 18 illustrates, generally at 1800, a state diagram for button operation, according to embodiments of the invention. A button, such as 1614 in FIG. 16, is designed to support multiple purpose functionality. In one or more embodiments, the descriptions of the functions supported by a single button, a touch slider, and a proximity sensor are illustrated by way of example. Other functionality can be provided by the button, touch sensor, and proximity sensor. Different numbers of buttons, sliders, and sensors can also be provided in various embodiments in order to provide the needed functionality for a given head wearable device. The functionality and state diagrams presented herein are provided merely by way of example and do not limit embodiments of the invention. Power ON/OFF Function 1802/1804 is illustrated as follows:

-   -   a) A power “ON” state at 1802 is entered with a short press of         the “Power Button” for a predetermined time (in one or more         embodiment the predetermined time is two (2) seconds) until an         “ON” indication light is activated. In one or more embodiments,         the “ON” indication light is a blue colored light. In the “ON”         state 1802 a user can, through voice command ask the system what         the battery power level is at. For example, a system can be         configured to return battery power level quantized to different         granularity. One example is a quantization to three (3) battery         power levels, i.e, low, medium, high. Other quantizations are         possible, and this example using three battery power levels is         given merely for illustration with no limitation implied         thereby. Alternatively, the system can be configured to notify         the user of the current battery power level via machine         generated audible voice message.     -   b) A power “OFF” state at 1804 is entered with a long press of         the “Power Button” for a predetermined time (in one or more         embodiment the predetermined time is three (3) seconds) until a         an “OFF” indication light is activated. In one or more         embodiments, the “OFF” indication light is a red colored light.         The system can be configured to notify the user that the system         is powering down to the “OFF” state via machine generated         audible voice message.         The pairing/unpaired functions 1806/1807 with a device, such as         a mobile phone, are illustrated as follows:     -   i. A press of the “Power Button” for a time longer than is         required to move to the OFF state, results in “PAIRING” the         system to a mobile device. For the purpose of the example given         herein, 5 seconds is a suitable time to configure the system for         “PAIRING,” noting that 5 seconds is longer than the time (2         seconds) required to move the system to the OFF state. Thus, in         operation, a user depresses the “Power Button” until a blue         colored light and a red colored light blink alternatively which         will pair the system with a mobile device, indicated at 1806.         After pairing, the system will play a machine generated voice         prompt telling the user that pairing was successful. The system         can be moved to the “UNPAIR” state at 1807 by depressing the         power for a time longer than is required for pairing. Thus         eight (8) seconds would accomplish moving the system to the         “UNPAIR” state at 1807. Different times can be chosen and those         predetermined times given herein are given merely for an example         and do not limit embodiments of the invention.     -   ii. After pairing successfully, a user can play music at 1808         and make a phone call at 1810 utilizing a wireless connection         between the head wearable device and a mobile phone or an MCU         (generically referred to as a device). Head wearable devices,         such as Smart Glasses will be turned off automatically after a         preset time if the connection fails. In one embodiment, provided         merely for example the preset time is three (3) minutes.     -   iii. When music is playing through the smart glasses at 1808, a         short press of the button will advance to the next song at 1812.         In one embodiment, provided merely for illustration, and with no         limitation implied thereby, a short press of the button         necessary to advance to the next song is less than two (2)         seconds.     -   iv. When there is an incoming call during music playback or when         in the idle state, a short press the button for less than a         predetermined time will answer the call at 1814. For the purpose         of illustration, and with no limitation implied thereby, a         predetermined time for a short press of the button is less than         2 seconds. In case a user presses the button longer than the         predetermined time, then the call is rejected at 1816.

FIG. 19 illustrates, generally at 1900, a state diagram for touch sensor operation, according to embodiments of the invention. In one or more embodiments, a touch sensor is configured with concurrent “slider” functionality and “tap” functionality. An example of a touch sensor is 1616 in FIG. 16.

In one or more embodiments, provided merely for example, and with no limitation implied thereby, a touch sensor supports two functions: touch slider, single tap and double tap operations. In other embodiments, a touch sensor can be configured to support more or less functionality than that of the sensor described herein. With reference to FIG. 19, a state diagram corresponding to touch sensor operations is illustrated. Volume control by slider 1930 is configured on an eyewear device 1940. The slider 1930 is configured to accept a “sliding” input registered by a user sliding a finger along the sensor region. In this example, the volume control has 8 levels (level 1 . . . level 8). A “quick slide” imparted to the touch slider results in an increase or a decrease in the volume by 1 level depending on a direction of the “quick slide.” For example, if a current volume is at level 3, a quick slide forward 1952/1954 increases the volume 1904 changing the volume from level 3 to level 4, where 1 represents minimum volume and 8 represents maximum volume. Similarly, a quick slide backward from level 3 results in a decrease in volume 1906 changing the volume thereby from level 3 to level 2.

“Slow slide” applied by a user to the touch slider means increase or decrease the volume continuously. For example, if the current volume is at level 3, a slow slide forward to the end of the touch sensor region increases volume 1904, changing it from level 1 to level 8. A slow slide forward to a middle of the touch sensor region, increases volume 1904, changing the volume from a level 1 to a level 4.

When the volume is at level 4, slow slide backward 1962/1964 to the end of the sensor region, decreases volume 1906, changing the volume from a level 4 to a level 1.

From an incoming phone call state 1920, sliding forward 1952/1954 results in answering an incoming call at 1924. From the incoming phone call state 1920, sliding backward 1962/1964 results in rejection of an incoming call at 1922.

A double tap executed by a user on the touch slider region 1930 of the smart glasses 1940 is used to activate or deactivate the wake-up chip. In one or more embodiments, if voice wake-up is in an “OFF” state then a double tap applied to the touch slider region changes the voice wake-up to an “ON” state 1910. Similarly, if voice wake-up is in an “ON” state 1910, then a double tap applied to the touch slider region changes the voice wake-up to the “OFF” state 1902.

In various embodiments, a single tap is used to play music by moving the system to a music “PLAY” state 1902 or to enter a music “PAUSE” state 1908, where music play is paused pending further input from the user. When in the “PAUSE” state, a subsequent single tap from the user moves control back to the “PLAY” state and music play resumes at 1902. Additional state changes are accomplished by subsequent single taps to move between PLAY” to PAUSE” and vice versa as desired.

FIG. 20 illustrates a state diagram, generally at 2000, for proximity sensor operation, according to embodiments of the invention. In various embodiments, a proximity sensor (such as 1618 in FIG. 16) is used to detect whether a user is wearing the head wearable device or has taken the head wearable device (eyewear) off. In one example, given merely for illustration, and with no limitation implied thereby, the logic for the sensor operation proceeds as follows. If the output of the proximity sensor is a “1” that means that the user is wearing the eyewear 2002. If the output of the proximity sensor is a “0” that means that the user has removed the eyewear 2004.

Logic is configured to turn “OFF” music play when the user removes the eyewear from the user's head. For example, if user has put on the eyewear 2002, then music will “PLAY” at 2006 controlled by either of the sensors described above that control the music play functionality. If the user removes the eyewear 2004, the proximity sensor will output “0,” when the “0” output has lasted for more than a predetermined time, the music will “STOP” and the system will enter a “PAUSE” state 2008 for music play. In one or more embodiments, the predetermined time required for the music to stop playing is five (5) seconds. The music will resume “PLAY” state 2006 if the user puts the eyewear back on, in which case the proximity sensor output changes to “1.”

If the eyewear should remain off of the user's head for more than a predetermined time, then the system is powered down into an “OFF” state at 2010. In one or more embodiments, the predetermined time required to power the system down while the user is not wearing the eyewear is ten (10) seconds or more. Those of ordinary skill in the art will recognize that the predetermined times given above are examples and that different predetermined times can be used in various embodiments. No limitation is implied by the times selected for the examples given herein.

FIG. 21A through. FIG. 21D illustrate locations for the touch sensor and the multi-function button. With reference to FIG. 21A, an eyewear device is illustrated at 2102 in perspective view with rear orientation. A multifunction button 2106 is shown located on an underside of a right temple 2108. A touch sensor area 2104 is shown located on an outer surface of the right temple 2108. Both the multifunction button 2106 and the touch sensor area 2104 provide functionality as described in conjunction with the figures above.

With reference to FIG. 21B, an eyewear device 2252 is illustrated in a forward oriented perspective view at 2200 and in side view at 2275. A multifunction button 2276 is shown located on an underside of a right temple 2278 of the eyewear device 2252. A touch sensor area 2254 is shown located on an outer surface of the right temple 2278. Both the multifunction button 2276 and the touch sensor area 2254 provide functionality as described in conjunction with the figures above.

With reference to FIG. 21C, an eyewear device is illustrated in side view at 2300. A touch sensor area 2304 is illustrated as a rectangular area on an outer side of the right temple 2378. Note that the touch sensor area 2304 can be provided in shapes other than rectangular. A rectangular shape for 2304 is provided merely for illustration with no limitation implied thereby. A user utilizes a finger 2306 to slide forward or backward to control volume as described above in conjunction with the preceding figures and to initiate taps as described above.

With reference to FIG. 21D, an eyewear device 2402 is illustrated in a side view at 2400. A multifunction button 2404 is illustrated on an under side of a right temple 2478. A user utilizes a finger 2406 to depress the button 2404 as described above in conjunction with the preceding figures in order to control functions of the eyewear system in 2402.

Note that the multi-function button and or the touch sensor area can be located in other positions on the head wearable device, such as, for example, on an outer surface of a temple, on a top surface of a temple, or on a left temple.

For example, in one or more embodiments, a multifunction button is located on a top surface of a right temple. In use, a user grasps the right temple with two fingers, one finger placed on a bottom surface of the temple and the other finger placed against a top surface of the temple. For example, in one scenario, the user places a right thumb against the underside of the right temple, a right middle finger is placed on a top surface of the right temple thereby grasping the right temple. With the right index finger the user can operate the multifunction button. Arranged in this fashion the multifunction button is set back from a plane of the front frame such that the button is aligned with and operable by the user's index finger when the temple as grasped as described above.

In various embodiments, such an arrangement of the multifunction button is more easily operated when the user is undergoing an activity such as bicycle riding and the user is operating the multifunction button.

In some embodiments, a bump, depression, or other shape of alignment mark is fashioned into the temple to serve as an alignment location for a user's finger or fingers relative to a location of the multifunction button. Placing a multifunction button a specified distance from an alignment location permits a user to quickly find the multifunction button when the eyewear is on the user's head. In some embodiments, the alignment is provided when a user grasps a temple with thumb and middle finger at the junction of the temple and the front frame.

While the multifunction button is shown on the right temple, the multifunction button can also be located on a left temple of the eyewear device. A left-handed user might prefer to have the multifunction button as well as the touch sensor located on a left temple, while a right-handed user might prefer to have the multifunction button and the touch sensor located on a right temple. Thus, embodiments of the invention are configured in either button/temple configuration.

Gesture Detection

In various embodiments, the hardware architecture includes a touch sensor and a multi-axis motion sensor as described above. In some embodiments, a nine (9) axis motion sensor is used. The sensor data is used to detect various head gestures. Once a head gesture is detected, a corresponding action will be taken by the system. In one example, when a phone call comes in, a user can nod his or her head in one direction, such as up and down to answer the call. Similarly, a head shake left-to-right or right-to-left is interpreted by the system to reject the call. For example, a phone call comes in, a user can put his or her finger on the touch sensor and then nod his or her head down to pick up the phone call. Or with a finger on the touch sensor, the user shakes his or her head to reject the call.

In some embodiments, the multi-axis sensor is used for posture detection of the user. In various embodiments, the sensors collect accelerometer data, gyroscope data, and magnetometer data and then pass the data to the system for processing using a software algorithm running on a central processing unit (CPU), DSP, etc. as described in conjunction with the figures above In some embodiments, sensors are configured using three orthogonal axes. These data are processed using one or more of; a software algorithm, a CPU, and a DSP to detect the posture of the user's head. In various embodiments, when the user's head is not in a proper position for a long time, a voice message is generated and broadcast via the speaker to the user. Such communications to the user permit the user to take corrective action and improve posture for example.

Audio Content

As described above, in various embodiments, a head wearable device is used in conjunction with a mobile device to facilitate phone calls with the system that is configured into the head wearable device (eyewear device). Content, such as music can be streamed via a mobile device to a head wearable device. The content stream can also originate in the “cloud,” i.e., the Internet, or local network and be streamed to the head wearable device. In addition, local storage configured either with the system (FIG. 16) or configured on the head wearable device for use by the system (FIG. 16) can be used to provide a source of content that is played for the user through the speaker(s) incorporated with the head wearable device. Thus, in various embodiments, content is played for a user through the head wearable device either in conjunction with a mobile device or in a standalone configuration without the mobile device.

Answering a Phone Call

Phone calls can be answered in various ways in various embodiments. A phone call can be answered and or terminated with the voice interface utilizing the local speech recognition system using control words such as “ANSWER” to receive a call and “GOODBYE,” for example, to end a call. Alternatively, a phone call can be answered with one or more of the physical sensors such as the “touch sensor” and or the “button.” Alternatively, a phone call can be answered through analysis of a head gesture utilizing data output from the accelerometers, gyroscope, etc. Note that a combination of one or more of the above (i.e., speech recognition, sensor output, and gesture identification) can be combined to answer a phone call. Similarly, one or more of the above can be combined to provide for selection and or playing of audio content for the user through the system incorporated into the head wearable device.

Command and Control

System control—utilizing a wake-up word to power the system up from a sleep state using a wake-up word, such as for example, “SOLOS”. Content control—“play running music,” “skip song,” “volume up,” “volume down,” etc. Telephone control—such as for example: “make a phone call to ‘name’” (phone number corresponding to ‘name’ e.g., can be selected from contacts), “volume up,” “volume down.” Information control—such as for example: “internet browsing,” checking for “temperature,” check “weather,” “navigation,” etc. These examples have been provided merely for illustration and do not limit embodiments of the invention.

Magnetometer

In various embodiments, a magnetometer is incorporated into a head wearable device. In some embodiments, the magnetometer is a three-axis magnetometer. The magnetometer in the head wearable device is used for navigation to ascertain an orientation of the user to the earth's magnetic field. A magnetometer mounted in a head wearable device, when on a user, has a fixed pointing direction that is aligned with the movement of the user. Thus, a magnetometer's output from a head wearable device will provide a more useful signal then a magnetometer that might be incorporated into a user's mobile phone because the mobile phone is not necessarily aligned with the direction that the user is pointing in.

In various embodiments, a magnetometer's output is used within an application program utilizing a map to display a user's direction and to rotate the digital map as the user's orientation to north changes, for example.

Accelerometer

In various embodiments, one or more accelerometers are provided in the head wearable device. In some embodiments, a three-axis accelerometer is provided.

Gyroscope

In various embodiments, one or more gyroscopes are provided in the head wearable device. In some embodiments, a three-axis gyroscope is provided.

Battery Housed in One or More Temples

In various embodiments, one or more batteries are provided to power the system and the one or more batteries are stored within a volume of a temple or temples. Batteries are constructed with chemistries such as Lithium Ion or other battery chemistries to support long life and to permit many recharge cycles over the life of the battery. Depending on the expected power needs for a head wearable device, several different sized temples can be provided for different applications. For example, some sports events might require six or more hours of “ON” time for a system. In such a situation, a large temple houses a long-life battery. A smaller volume temple will house a smaller battery having a shorter useful time between recharge cycles. Head wearable devices are configured for various uses such as sporting activities, business uses, home, and commercial uses. Some non-limiting examples of sporting activities are, but are not limited to, bicycling, running, skiing, boating, hiking, etc.

System Distribution Across the Head Wearable Device

In one or more embodiments, the electronics system of a head wearable device is distributed across a left temple, a front frame, and a right temple. In one or more embodiments, a left temple houses a battery, one or more microphones, and at least one speaker. A right temple houses a battery, system electronics, one or microphones, and at least one speaker. In some embodiments, electrical connections between components of the system (temples and front frame) are provided in the form of removable connectors. In some embodiments, these connectors can be hinged.

For purposes of discussing and understanding the different embodiments, it is to be understood that various terms are used by those knowledgeable in the art to describe techniques and approaches. Furthermore, in the description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of an embodiment. It will be evident, however, to one of ordinary skill in the art that an embodiment may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring various embodiments. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention.

Some portions of the description may be presented in terms of algorithms and symbolic representations of operations on, for example, data bits within a computer memory. These algorithmic descriptions and representations are the means used by those of ordinary skill in the data processing arts to most effectively convey the substance of their work to others of ordinary skill in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of acts leading to a desired result. The acts are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, can refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission, or display devices.

An apparatus for performing the operations herein can implement the present invention. This apparatus may be specially constructed for the required purposes, or it may comprise a general-purpose computer, selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but not limited to, any type of disk including floppy disks, hard disks, optical disks, compact disk-read only memories (CD-ROMs), and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), dynamic random access memories (DRAM), electrically programmable read-only memories (EPROM)s, electrically erasable programmable read-only memories (EEPROMs), FLASH memories, magnetic or optical cards, RAID, etc., or any type of media suitable for storing electronic instructions either local to the computer or remote to the computer.

The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general-purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method. For example, any of the methods according to the embodiments can be implemented in hard-wired circuitry, by programming a general-purpose processor, or by any combination of hardware and software. One of ordinary skill in the art will immediately appreciate that the embodiments can be practiced with computer system configurations other than those described, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, digital signal processing (DSP) devices, set top boxes, network PCs, minicomputers, mainframe computers, and the like. The embodiments can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network.

The methods herein may be implemented using computer software. If written in a programming language conforming to a recognized standard, sequences of instructions designed to implement the methods can be compiled for execution on a variety of hardware platforms and for interface to a variety of operating systems. In addition, the embodiments are not described with reference to any particular programming language. It will be appreciated that a variety of programming languages may be used to implement the teachings of the embodiments as described herein. Furthermore, it is common in the art to speak of software, in one form or another (e.g., program, procedure, application, driver, . . . ), as taking an action or causing a result. Such expressions are merely a shorthand way of saying that execution of the software by a computer causes the processor of the computer to perform an action or produce a result.

It is to be understood that various terms and techniques are used by those knowledgeable in the art to describe communications, protocols, applications, implementations, mechanisms, etc. One such technique is the description of an implementation of a technique in terms of an algorithm or mathematical expression. That is, while the technique may be, for example, implemented as executing code on a computer, the expression of that technique may be more aptly and succinctly conveyed and communicated as a formula, algorithm, or mathematical expression. Thus, one of ordinary skill in the art would recognize a block denoting A+B=C as an additive function whose implementation in hardware and/or software would take two inputs (A and B) and produce a summation output (C). Thus, the use of formula, algorithm, or mathematical expression as descriptions is to be understood as having a physical representation in at least hardware and/or software (such as a computer system in which the techniques of the present invention may be practiced as well as implemented as an embodiment).

Non-transitory machine-readable media is understood to include any mechanism for storing information (such as program code, etc.) in a form readable by a machine (e.g., a computer). For example, a machine-readable medium, synonymously referred to as a computer-readable medium, includes read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; except electrical, optical, acoustical or other forms of transmitting information via propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.); etc.

As used in this description, “one embodiment” or “an embodiment” or similar phrases means that the feature(s) being described are included in at least one embodiment of the invention. References to “one embodiment” in this description do not necessarily refer to the same embodiment; however, neither are such embodiments mutually exclusive. Nor does “one embodiment” imply that there is but a single embodiment of the invention. For example, a feature, structure, act, etc. described in “one embodiment” may also be included in other embodiments. Thus, the invention may include a variety of combinations and/or integrations of the embodiments described herein.

While the invention has been described in terms of several embodiments, those of skill in the art will recognize that the invention is not limited to the embodiments described, but can be practiced with modification and alteration within the spirit and scope of the appended claims. The description is thus to be regarded as illustrative instead of limiting.
